Hanasaari shut down last year and Salmisaari is going to be closed by april next year, after that Helsinki will have no coal or pellet power plants left.

Electricity generation isn't the main problem, but that those plants were responsible for a huge majority of central heating in Helsinki (iirc they were designed on purpose to be so inefficient they generated 2/3rds of their output as heat for that use). That's why they are building wacky solutions like huge underground lakes and stuff
